Chain and Sprocket Specs & Calculations
Benefits to the New Gearbox Design
The new box has the following benefits:
- The box is totally reversible in any orientation for the four wheels.
- The same motor sits adjacent to the drive shaft instead of in-line, making the box only 20" long instead of 30"
- This enables us to narrow the wheelbase considerably (which is definitely needed in order to fit the tractor safely on any trailer other than a semi).
- Still modular - you can use it in other applications as well.
- Gives the option for expansion into narrower wheel-based vehicles (Such as the Car or MicroTrac)
- Allows for potential gear shifting & speedier movement if you want to add different size sprockets
- Stronger and shorter 3" drive shaft instead of 2" (Less likely to break)
- This also means that using skid steering becomes a viable option again
- Easily serviceable:
- Both sides are open with plenty of lengthwise room to slip the motor, sprockets, and bearings out if needed.
- Hydraulic motor inputs/outputs easily accessible.
- Clamp is essentially just a large C Clamp with two long bolts. When removed, the whole box comes out.
